How do you distribute your $ on cables? in ?

I like to use a really nice IC (AN VX $980) from source to my integrated amp. It is cheaper to do than spend it on speaker cables (Lexus bi wire $700) and this way you get the best signal to the amplifier to begin with.

I have a VenHaus DIY PC and it is so good I forgot about upgrading it - for about $60 each.

so in your opinion, the most effective is the source signal cable, isn't it?

how effective are power cables compared to speaker and interconnects?
